Should logic be taught in elementary?

[festive1]

Isn't the best way to teach logic just Mathematics?

My first grader (he's going into 2nd grade in a couple weeks) gets frustrated because of the focus on reading and writing and he's a math guy. Reading and writing are important, but the US educational system doesn't put enough emphasis on math. Our school district doesn't allow kids who are good at math to do move on to more advanced stuff because they aren't doing equally well in the reading/writing arena. So my kid spends half the day frustrated with the reading and writing and bored for part of the day (because they don't equally divide time between reading/writing and math) with the easy math... No one wins.
